Elimination of apoptotic granulosa cells by intact granulosa cells and macrophages in atretic mature follicles of the guinea pig ovary.
Phagocytic cells disposing of dying granulosa cells in the atretic ovarian follicles were morphologically studied in guinea pig ovaries at various stages of estrous cycle. Epon embedded semithin sections stained with toluidine blue were observed with a light microscope, and ultrathin sections were examined under a transmission electron microscope. Frozen sections were processed for acid phospha...
متن کاملChanges in granulosa cells gene expression associated with growth, plateau and atretic phases in medium bovine follicles
BACKGROUND The objective of this study was to build the transcriptomic profile of granulosa cells originating from follicles 6 to 9 mm in diameter in dairy cattle using microarrays. METHODS Granulosa cells originating from three different phases of antral follicle growth were compared: growing (G), plateau (P) and atresia (A), as categorized by flow cytometry profiles of DNA. The growing and ...
متن کاملGlobal gene expression in granulosa cells of growing, plateau and atretic dominant follicles in cattle
BACKGROUND The physiological state of the dominant follicle is important as it may be linked to the competence of the oocyte within. The objective of this study was to analyze, by transcriptomic analysis, the changes occurring in granulosa cells from dominant follicles at different phases of follicular growth. METHODS Granulosa cells were collected from slaughterhouse dairy cattle follicles w...
متن کاملAge-dependent changes in the expression of superoxide dismutases and catalase are associated with ultrastructural modifications in human granulosa cells.
Limited knowledge exists about changes in follicle quality associated with age. The aim of this work was to investigate whether ageing may cause oxidative stress-mediated alterations in human granulosa cells (GCs) from periovulatory follicles. GCs employed in this study were obtained from follicular aspirates of 20 younger women (range 27-32 years) and 20 older women (range 38-41 years) undergo...
متن کاملThe Ultrastructural Changes of the Sertoli and Leydig Cells Following Streptozotocin Induced Diabetes
Objective(s) This investigation was conducted to evaluate the effects of diabetes on the structure and function of testicular tissue. Materials and Methods Diabetes was induced in male adult rats by a single intraperitoneal injection of streptozotocin. Body and testicular weight, hormonal analyses, histological and ultrastructural analyses were measured. Results The body and testicular we...
